I found RealCalc back in 2013 and it immediately became a home screen staple. A few years later, I became a paying customer for RealCalc Plus, not because I needed more features, but because I felt that I should reward the developer for the use I was getting from the app. Now, in 2021, I still have it on my home screen and still use it as much now as I did then.

This is the second best calculator I have ever used (the best being the TI-89 Titanium, which, to be fair, is almost a rediculous comparison). In fact, if the developers were to add graphing functions (hint hint) it could easily rival the Titanium. The free version is probably more calculator than most people need, but definitely buy the Plus version, as that's the best way to support the developers.
